Goyang Geumjeong Cave massacre

The Goyang Geumjeong Cave massacre occurred from 9 to 31 October 1950 during the Korean War. After the Second Battle of Seoul, South Korean authorities arrested and summarily executed 153 unarmed Korean civilians along with their families on suspicion of being communist North Korean sympathizers, killing them in a cave in Goyang, Geonggi-do in northwestern South Korea. The bodies were not excavated until 1995, and the South Korean government was forced to apologize, pay reparations, and fund a memorial to the massacre's victims in 2011.
